Advance Multitouch - patent everything under the sun

Came across this here at Engadget.  Seems that Apple is really pushing hard with all thsi multi touch technology.  I'm not really sure how or why you can patent gestures but it seems that they're doing it.  Apple products are great, but you gotta love how Apple can scoff off anyone having innovation asides from them, when they've taken all the basic ideas and patented them.  But I suppose if you can patent the pinch motion you can patent anything.  Heck I think for a while Sega had a patent for changing cameras in racing games.
